Vagrant Master and Slave Boxes - SSH Key setup

Question

I'm trying to setup ssh key login, so I can type ssh slave01 without password to ssh into the slave machine, but I'm having trouble setting it up here. The master and slave are Vagrant boxes running Ubuntu.

The master box has the following settings

vagrant@vagrant-ubuntu-trusty-64:~$ ifconfig
          ...
          inet addr:192.168.33.10  Bcast:192.168.33.255

vagrant@vagrant-ubuntu-trusty-64:~$ cat /etc/hosts
...
192.168.33.10 master
192.168.33.12 slave01
192.168.33.13 slave02

vagrant@vagrant-ubuntu-trusty-64:~/.ssh$ cat id_rsa.pub

The slave the following settings

vagrant@vagrant-ubuntu-trusty-64:~$ ifconfig

When I run the following from the command line in Master, it is keep asking for the password. I am not sure why it is doing this.

vagrant@vagrant-ubuntu-trusty-64:~/.ssh$ ssh slave01
vagrant@slave01's password:

Try using ssh-copy-id to move your ssh key between machines. You likely did not set the proper chmod permissions on the directories.
